Re: first 7mag loads

when shoot them i will let you know how they work. but in all fairness to them barnes reccomends.050 off the lands, i do not know how to tell depth off the lands so i set them a a length that "looks" right and that cycles well in my rifle. i have done this with all of my rifles with succes.

    You may be surprised by the accuracy of the accubond and the hornady.. The sierra GK 160 I´ve shot in mine never did too well though.

    For accuracy and high BC go to a 160 accubond or try the 162 a max. also.

    Alg, i have had excellant accuracy with the accubond out of my 270, 270wsm and my dads 7 ultra mag. all of them will shoot under 1/2 inch. the 270 does 1/2 inch with factory ammo!

    Re: first 7mag loads

    If you would like a simple tool to aid in seating depth, you can get a Stoney Point bullet depth gauge from Midwayusa.com

    It is good that you've had success by visual inspection in the past. However, if you want to know the numbers, I recommend a gauge. It comes with any dummy brass you want and extra calibers are not that expensive.

    When I checked my 7mag with the 120 tsx, it was seated so far out that minimal bearing surface of the bullet was in the neck. Not enough tension IMO. The rifle still printed 1.2" groups but that is not what I'm looking for. As I seated it deeper, the groups spread.

    Ok, but you mentioned not knowing how far off the lands. That is why I mentioned the SP gauge. That will tell you base to ogive which is what I thought you wanted to know.

    Re: first 7mag loads

    First loads on a 7 Mag, it is a very accurate cartridge. First of all the 140g Sierra is a bullet better designed for the 7/08 than the 7 Mag, it will detonate. The 160g BT sp on the other hand will not.

    In all cases, bullets seated to touch the lands with a Davidson ojive guage.

    The best loads that I have found over the years in many 7 mags are as follows:

    140g Nosler either BT or Accubond
    Rem brass
    9 1/2 primer
    64-65g of IMR 4350

    150g Nosler BT
    63.0g of IMR 4350
    Rem brass
    9 1/2

    160g Sierra or 162g Hornady
    Remm brass
    9 1/2
    61.0g of IMR 4350

    In all cases, bullets seated to touch the lands!

    If the rifle does not shoot these loads, sell the gun, no Sxxt!
